Conclutions: Under ischemic condition, the decrease of Iks could prolong the mid-late repolarization phase of APD. It could cause EAD and then arouse TdP. Because the decrease of M cell was significantly greater than that of sub-endocardial myocytes and sub-epicardial myocytes, it could increase TDR. Cardiac arrhythmias could last due to reentrance that secondary the increase of TDR.

缺血时，心肌细胞的Iks电流减弱，使得细胞动作电位复极中后期延长，容易出现EAD并引发TdP；由于M细胞的Iks电流减弱程度明显大于心内、外膜细胞，造成心室跨壁复极离散度增加，有利于折返的发生，使得心律失常得以持续。
